Abstract

A 33-year-old female from Uzbekistan visited our hospital with symptoms of right blurred vision, ocular pain which were exacerbated by ocular movement, and exophthalmosis for 2 months. Preoperative facial CT scan showed 3.2x2.4cm-sized cystic mass at the right retrobulbar area. The mass was located at temporal aspect of retrobulbar area and displaced optic nerve medially. Right eyeball was anteriorly displaced at the degree of 7mm than left one and intra-ocular pressure was raised as 32 mmHg compared with left one which estimated at 15 mmHg. Removal of cytic mass was performed using lateral orbitotomy. After incision was made through Stellard- Wright incision, dissection was done to lateral outer orbital periosteum then the periosteum each side of lateral orbit were dissected for lateral orbitotomy. Removal of lateral orbital wall, which was enough to removal cystic mass, by lateral orbitotomy, was done then lateral rectus muscle was divided without cutting. Cystic mass could be resected after lateral rectus muscle was divided and resected lateral orbital bone piece was re-located and fixed by absorbable miniplate. A satisfactory result could be obtained by this procedure. Postoperative intra-ocular pressure was lowerd as 15mm Hg and exophthalmosis was corrected at the degree of 1mm on Hertel's exophthalmometery and visual acuity improved at the degree of 1.0 on optomety compared with preoperative one which estimated 0.04. Preoperative symptoms such as ocular pain, foreign body sensation, headache were disappeared without any complication just like retrobulbar hemorrhage, infection etc.
